The invention relates to a
clothianidin synergia
solubility granula and a preparation method thereof. The granula is prepared from the following components by weight percent: 1-20 percent of
clothianidin, 1-10 percent of a dispersing agent, 1-5 percent of a
wetting agent, 2-4 percent of a binder, 1-3 percent of a stabilizer, 1-3 percent of a synergist and the balance of fillings. The preparation method comprises the following steps of: carrying out coarse
grinding on the
clothianidin, dispersing agent,
wetting agent, stabilizer and fillings, stirring and mixing, then carrying out ultrafine
grinding to obtain ultrafine
powder with the grain size less than 15 micrometers; and adding a binder for pelleting, screening by using a vibrating screen, and
drying to obtain a product. The clothianidin synergia
solubility granula has the advantages of the
solid preparation and liquid pharmaceutical preparations; at the same time, due to the addition of synergist, the clothianidin synergia
solubility granula has obviously control efficiency on the common
crop injurious insects such as
Hemiptera, coleopteran, diptera and certain lepidoptera pests, has the insecticidal
efficacy improved by 1.4-1.5 times compared with that of the 50% clothianidin
aqueous dispersion granula, and improves the
utilization rate of the active constituent clothianidin.
